The iMac "M1" 8-Core CPU/8-Core GPU/4 USB-C Shaped Ports (2021) model features a 5-nm 3.2 GHz Apple M1 processor with 8 cores (4 performance cores and 4 efficiency cores), an 8-core GPU, a 16-core Neural Engine, 8 GB of onboard RAM, and a 256 GB or 512 GB onboard SSD. Both the RAM and the SSD could be upgraded at the time of initial system purchase, but not subsequently.
This all is housed in a wafer thin aluminum case with flat edges that includes a 23.5" 4480x2520, 218 PPI, LED-backlit, "True Tone" widescreen "Retina 4.5K" display mounted on a svelte aluminum stand. This specific model was offered in the choice of six two-tone color options -- blue, green (pictured), pink, yellow, orange, and purple -- as well as a "classic" uniform silver color. It also has an integrated 1080p FaceTime HD camera, a "studio-quality three-mic array" and a "high-fidelity six-speaker system" that supports Spatial Audio with Dolby Atmos.
Connectivity includes two Thunderbolt / USB 4 ports and two USB 3 ports (all with a USB-C connector), a 3.5 mm headphone jack conveniently mounted on the left edge of the display, Wi-Fi 6 (802.11ax), and Bluetooth 5.0. Gigabit Ethernet is provided by default via a port on the power brick.
Compared to its predecessor, the "2021 M1" iMac models have little in common and instead feature an all new external design and a completely different internal architecture that no longer supports internal upgrades at all.
By default, this specific "2021 M1" iMac shipped with a small, color matched aluminum wireless "Magic Keyboard with Touch ID" without a numeric keypad and a wireless "Magic Mouse" with multi-touch surface support. For an extra US$30 at the time of system purchase, you could substitute the stock keyboard for a "Magic Keyboard with Touch ID and Numeric Keypad". You also could substitute the Magic Mouse for a Magic Trackpad for an extra US$50, which provides multi-touch input and Force Touch support, or include both a Magic Mouse and a Magic Trackpad for an extra US$129.
